For a much bigger car with similar power, a 340 1.4 is surprisingly brisk... the engine is 'eager', and the gearing is good. It's never going to be anything other than 'slow', though.
Having said that, drive it hard, and you can keep up with fairly fast moving traffic. Particularly with the traction advantage, you can cause some upset at the lights. Ryan took out an e46 M3 at the lights the other week - if he pulls up on the right, he's fair game
1.0 or 1.2 superminis I randomly meet on-road, I assume I can out-accelerate. A Corsa (A) GSI (1.6 16v?) pulled away from me quite cleanly, but it was hardly a crushing defeat. The SRI (1.4 16v?) would have been much closer, I suspect, and I can't see that a 1.2 would win by very much, if at all. If it were a race situation, of course, you lose the element of surprise, which - as Ryan showed - can be good for +260hp
cheers
